IVOCLAR VIVADENT refines grindings, bench sweeps, polishings and metal scraps. All received precious metal scrap is carefully weighed by two people using calibrated scales accurate to .001-oz. to ensure material items and weights are checked against customers’ provided information. The company uses the traditional fire assay still regarded by global bullion dealers as the most accurate method. Platinum and palladium are determined by standard wet gravimetric and/or specialized instrumental techniques such as ICAP, Mass Spectrometer or X-ray. Settlement is calculated based on recovered net metal content and is valued at set published metals markets.
